人们试图寻找产生二十碳五烯酸（EPA）的微生物。在筛选出的大约7000种细菌菌株中，有112种或多或少地表现出这种活性。其中大多数是从海洋鱼类的肠道内容物中分离出来的，这些海洋鱼类的体内脂质中含有高水平的EPA。从太平洋鲭鱼中分离到一株EPA高产菌，其EPA产量为3.8 ~ 10.8mg/g干细胞，EPA占总脂肪酸的比例为27.8 ~ 36.3%。该菌株为革兰氏阴性菌，运动型，专性好氧，短杆状，推测为与交替单胞菌属相近的一个新种。
Attempts were made to find eicosapentaenoic acid (EPA) -producing microorganisms. Out of some 7, 000 bacterial strains screened, 112 of them showed more or less this activity. Most of them were isolated from intestinal contents of marine fishes which were known to contain high levels of EPA in their body lipid. A bacterial strain isolated from the Pacific mackerel Pneurnatophorus japonicus showed a high productivity of EPA (3.8 to 10.8mg/g dry cells) and also a high ratio of EPA to total fatty acids (27.8 to 36.3%). The strain was Gram-negative, motile, obligate aerobic and short rod-shaped, which we judge it to be a new species close to genus Alteromonas.
